Supercooled Water - More on Icing
This question is a question on physcial phenomena, NOT on regulation (so
I am starting a new thread). As I understand it, icing happens between +2C and -10C. Assuming this is correct, I have three questions. (a) Does that mean one is relatively safe if the surface temperature is below -10C (and there is no temperature inversion, meaning that the temperature is known to decrease as one goes up in altitude)? (b) Is icing from 0C to +2C a possibility only when your aircraft skin is colder than 0C (probably because you are descending from altitude)? Or is there some other condition where this is possible? (c) I have been told that icing is possible from -10C to 0C because water sometimes get "super-cooled" (which I assume means that water gets below freezing, but does not form ice for some reason). Is that right? If so, under what atmospheric conditions does water get super-cooled? |
